In addressing the goal for sustainability in the construction industry, the very materials used for construction and the methods utilized to implement said materials must be analyzed. Specifically, some traditional residential construction materials consist of wood, steel, and concrete. Because these materials vary in their levels of sustainability, there is a need to develop and explore new or other materials that can be used for residential construction. The primary purpose of this paper is to provide a review of interlocking earthen masonry units (IEMU) as an alternative option for residential building construction. This is in an effort to explore the variables impacting their existing and potential applications as sustainable materials and a method for residential building construction. IEMU's are then examined under the triple bottom line (TBL) sustainability framework which includes analyzing the environmental, economic, and social sustainability of IEMU's. The findings of this review may lead to further progression in the development of a framework for evaluating U.S. stakeholder adoption of IEMU's and potential implementation in U.S. residential construction.

(Background)In modern industrial society, the design industry failed to observe the law of nature, destructing it. Regardless its intention, the design industry destructed the environment so that it can't maintain the future life because of waste and disaster. For the purpose, it is important to adopt the technology to reuse the waste resource generated by building or minimize the damage to environment for the resource that can't be recycled. (Methods)On the assumption that the material and resource can be an alternative plan for the design that can make environment be sustained, the study analyzed materials and resources out of superior office space of USA, which were selected by LEED Green Building Rating System. (Results)The analysis result revealed that all cases reused main structural part of existing building and indoor and various materials were reused or recycled. Especially, the materials without or with low amount of VOCs and formaldehyde were used. In order to reduce construction waste, the finish of existing building was exposed as it was, 50% of reused materials were used or disassemblable materials were used. When regional materials are used, there is an advantage to reduce transportation cost and recycle the materials rapidly. Lastly, the environment-friendly certified by FSC was used in all cases. (Conclusion)After all, the material is one of the space design strategies sensitive to environment so it is important to select good material. Harmless, environment-friendly materials applied to sustainable office space contribute to the creation of healthy environment. In addition, the use of recycled materials and reused materials to minimize waste is also essential factor for creating sustainable space.

Tall buildings are built with an abundant amount of materials, including structural materials, coming from our limited natural resources. Tall buildings that began from about 10-story tall office towers have evolved to over 150-story tall mixed-use megastructures. As a building becomes taller, structural material requirement to resist lateral wind loads becomes exponentially larger. Therefore, it is crucial to employ efficient structural systems and optimize their design, which will contribute to sustainable vertical built environments through preservation of resources. Tube type structures with large perimeter diagonals are among the most efficient structural systems for tall buildings. Developments of braced tube, braced megatube, diagrid structures, and their optimal design strategies are reviewed. Superframed conjoined towers, produced by interconnecting multiple clustered braced tubes, are presented as a new design direction to achieve not only structural but also architectural and social sustainable design goals.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

Most of current building materials are made of organic compounds or at least made with chemical treatments. Though easy to use and comparatively pay less, those materials are generally not enviornmentally sound. VOC is one of harmful effects. On contrary, natural materials such as soil are usually eco-friendly, and environmentally sustainable as well if not treated in autoclaves. Acoustica materials made of such environmentally sound and sustainable could be widely used. It is aimed to prove that soil based materials could be effectively used in acoustical fields rather than the other usual materials. Experiments with various types of soil blocks and soil plaster were performed. It is proved that the soil plaster has better apsorption features than cement plaster. Soil blocks have higher absorption cofficients than soil plaster, due to the thickness, and the absorption characteristics can be controlled by the design of the blocks.
